Abstract

The utility model discloses a V-shaped turning type reed structure, and is mainly composed of a reed and a tablet forming structure; the reed is a V shape, forming three end regions; wherein two end regions of A end and B end are fixed at one side; the end point of C end at the other side is arranged with a point contact which constantly breaks with the contact at the lower part; a tablet-forming structure, which is composed of a drive ring and a central drive rod, is arranged on the reed; the drive ring is arranged on the middle part of the integrated reed at the lower part; the central drive rod is arranged on an extensional turning point which C end corresponds to a central fork part; therefore the utility model has the advantages of simple and compact structure, convenient using, reliability, high assembling precision, simple processing, low manufacturing cost, etc.

Description

The convertible reed structure of V-arrangement

Technical field

The utility model relates to the reed contact-making switch device on a kind of pressure switch or the similar products, belong to mechanical type touch switch device.

Background technology

In the prior art, the reed contact-making switch structure of pressure switch as shown in Figure 1, it is made up of the compressing tablet mechanism on reed 11,12 and top up and down, is correspondingly provided with electric contact 13 on the reed.Described compressing tablet mechanism is made of transmission ring 14 and middle drive link 15.Transmission ring 14 contacts with upper reed plate 11, and during the low pressure action, transmission ring 14 promotes upper reed plate 11 downwards and makes the contact of power-on and power-off contact, circuit turn-on; Drive link 15 contacts with following reed 12, and during the high pressure action, reed 12 separated two contacts that contacted under drive link promoted downwards, and circuit disconnects.In addition, tri-state switch in press and adopt independently actuating mechanism.The reed contact-making switch of said structure has adopted at least two movable contact springs basically and has driven work by compressing tablet mechanism respectively, thereby structure is comparatively complicated, carries out the action underaction, and poor reliability, manufacturing cost are also high.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, low cost of manufacture, the high convertible reed structure of V-arrangement of assembling installation accuracy.It mainly is made up of reed and compressing tablet mechanism, and the V-shaped shape of described reed forms three ends, and wherein two end side a and bs of a side are fixed, and the end points of end side C end is provided with a contact.

Be provided with electric contact below the described C end and open, be provided with the compressing tablet mechanism that forms by transmission ring and middle drive link above the reed with the contact normal off of bottom.

Described transmission ring is positioned at above the centre of the whole reed in bottom, and middle drive link is positioned at above the overturn point of C end corresponding to middle fork one extension.

The utility model compared with prior art, have simple in structure, compact, easy to use, reliable, the assembly precision height, product processing is simple, characteristics such as low cost of manufacture.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: Fig. 2, shown in Figure 3, the utility model mainly are made up of reed 21 and compressing tablet mechanism.Reed 21 V-shaped shapes are formed with three ends, and two end A ends 22 of a side wherein and B end 23 are fixing; Be provided with electric contact 25 below the C of the end side end 24, it and following contact 26 normal offs are opened.Be positioned at and be provided with the compressing tablet mechanism that is made up of transmission ring 27 and drive link 28 above the reed 21, transmission ring 27 is positioned at the centre position of the whole reed 21 in bottom, and during low pressure, transmission ring 27 presses down, and reed 21 is moved down, and electric contact 25 contacts with contact 26, the circuit connection.Middle drive link 28 is positioned at above C end 24 overturn point 29 corresponding to middle fork extension; During high pressure, middle drive link 28 presses down, and reed 21 forms a perk shape, i.e. upset makes electric contact 25 and following contact 26 disconnections, and circuit disconnects.
